Disclosed is a method of continuously determining the perimeter of an elongated object of generally uniform cross section which comprises wrapping the object with a sheet of flexible material having a pair of detectable parallel lines formed thereon, such that the lines extend axially parallel to the object, placing detection means in position to detect the lines, the detection means being capable of determining the distance between the lines, moving the object and the detection means relative to each other in a manner such that continuous detection of the lines and measurement of the distance therebetween occurs, and correlating the measured distance between the lines to the perimeter of said object.

Method for continuously measuring the perimeter of wrapped objects

Disclosed is a method of continuously determining the perimeter of an elongated object of generally uniform cross-section which comprises wrapping the object with a sheet of flexible material having a single band imprinted thereon in such manner that the single band extends axially parallel to the object and becomes partially obscured by an overlapping edge of the sheet, placing detection means in position to detect the width of the unobscured portion of the single band, the detection means being capable of determining the width of the unobscured portion of the single band, moving the object and the detection means relative to each other in a manner such that continuous detection of the single band and the measurement of the width of the unobscured portion of the single band occurs and correlating the measured width of the unobscured portion of the band to the perimeter of the object.

Disclosed is a method of moving a roll out of contact with a work-piece in response to its developing a slower speed than normal while being driven by frictional engagement with the work-piece which comprises

Yarn monitoring process

Disclosed is a method of monitoring planar sections of material having generally parallel crimps, the material having a longitudinal dimension extending generally perpendicular to the crimps and a transverse dimension generally parallel to the crimps. The material, such as a bundle of crimped fibers or tow, generally defines a plane, and the method comprises

Process for monitoring crimped material

Disclosed are a method and apparatus for making area measurements of an image on a kinescope screen. Scan lines of the kinescope are divided into a series of pulses by a switching device. The pulses within the image are counted. The number of pulses counted within the image is an indication of the area of the image. The size of the image may be determined in conventional units by comparing the number of pulses counted within the image to the number of pulses known to represent a given area.

Electronic measuring method and apparatus

Disclosed is a method for characterizing crimped tow for subsequent identification or quality control comprising the steps of obtaining length measurements of the individual crimps in a sample of the tow, graphically representing the measurement distribution of a sufficient quantity of the tow until a pattern is established, and using the pattern as a standard against which other tow is compared.

Inspection of elongated material

Disclosed are a method and apparatus for determining the deviation of an image from a predetermined position on a kinescope screen. This method and apparatus is useful, for example, in centering an image on the screen. The scan lines of the kinescope are divided into a series of pulses. The pulses within the image on each side of a reference line or X-Y coordinate system are counted and compared. The ratio of the pulses is an indication of the area of the image on each side, and suitable adjustments may be made in the position of the image to center it with respect to the reference line.

Electronic positioning method and apparatus

A continuous process is disclosed for treating a viscous polymer solution prior to being introduced into a spinnerette for producing fibers. The treatment comprises:

Process for removing impurities from polymer solutions

Apparatus and method are disclosed for determining the level of a light-reflecting substance with regard to a reference point. The apparatus and method comprise directing a beam of light at the substance, receiving the diffuse reflected light on an arrangement of photoelectric sensor elements in a manner such that displacement of the reflected light from a predetermined position on the sensor element arrangement is sensed electronically, generating an electrical signal which is proportional to the displacement of the reflected beam from the predetermined position on the element arrangement, and using the electrical signal to determine the amount of deviation of the level of the substance from a predetermined reference point.

Measurement of material level in vessels

Apparatus and method are described for inspecting elongated material such as strands, sheets, bundles or webs for the presence of surface irregularities, count of irregularities within a given length and angle of irregularities such as in the case of crimped fiber. A light source is used to form light areas and shadowed areas of the elongated material. A television camera produces a video signal of the light and shadowed areas and such signal is electronically analyzed with respect to number of alternating light and dark areas within a given length, and the relative widths of such light and dark areas, from which information can be obtained to confirm presence of irregularities, count or frequency, and angle. A filter is disclosed for removing relatively low frequency signals caused by unintentional shadowing from the useful signals so that the accuracy of the apparatus is improved.

Population and/or profile data of bodies contained within a transparent mass are obtained using a schlieren optical system in combination with a television camera, video analyzer, analog signal comparator and digital computer. The bodies, normally indistinguishable from the transparent mass by the unaided eye, are detected by the schlieren optical system and a television camera produces a video signal which is suitably processed, by the apparatus and method described, for introducing into a digital computer. The invention is especially useful as a means for quality control in various chemical operations.

Population and profile data of bodies in a transparent mass

Population and profile data of transparent bodies contained within a transparent mass are obtained using a schlieren optical system in combination with a television camera and receiver. The transparent bodies, normally indistinguishable from the transparent mass by the unaided eye, are detected by the schlieren optical system and then magnified and contrasted on the television receiver. The invention is especially useful as a means for quality control in various chemical operations.
